Hi again,

Oh yes, I should add that we are not using any tracking. That is we have
development CAVElib licenses for the Linux boxes so we are using simulator
mode for interaction... That may be the significant difference (although
Andreas said they do not get good performance even in simulator mode).

Cheers,

        Brian
